Hi Mădălin,

Thanks for the patch.

Despite all the test inputs the test suite is not actually run:

     "This package is a library to enable flexible and scalable operations on
genomic interval dataframes in Python.  @code{python-bioframe} enables access;
to a rich set of dataframe operations.  Working in Python enables rapid
visualization (e.g. matplotlib, seaborn) and iteration of genomic analyses.")

Please note that the lack of requirements.txt on pypi shouldn’t be an
obstacle to use the sources from pypi.  It should build just as well.
